Carnival worker kidnapped

A carnival worker has been kidnapped after an Eid Festival at Lakemba in Sydney's south-west.

The man was returning to his Amusement Hire Services business at Clyde when three armed men stormed in just before midnight.

Police say the intruders took cash and forced him into a car, before being bundling him out on the M-7.

Worker, Ricky, says they also threatened his colleagues.

"They just put the guns to the other two boys' head and told them to search their pockets and took everything out of the pockets and then they took their phones and then threw them in the front yard somewhere and then they were tied up in the office," he said.

"They took the boss away and left the other two tied up in the office and they raced around to the garage and rang the police."

Two hours earlier, a brawl broke out at the festival at Parry Park.

Police say a security guard and another man were bashed with a metal pole when they intervened.
